I started on Rich van Konynenburg's simplified methylation protocol this spring. I ordered the lecithin from a well known source. The first bottle smelled somewhat rancid. Now that I reordered, the second bottle smells the same way. I don't think this can be good for me. I contacted the company and someone is suppose to get back to me (It is still early for a reply). I know RVK recommended Smart Youthful Energy as being better, but I am already spending a small fortune on medicines and supplements. Any comments on my concerns? Can you recommend a source of lecithin that doesn't smell rancid and is reasonably priced?
